ATTACHMENT FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 348,546, datedSeptember 7, 1886,

(No model.)

To aZZ whom it may concern:

Be it known that I, GoRNELrUs G. COMEGYS, a resident of Cincinnati,Hamilton county, State of Ohio, have invented certain new and usefulImprovements in Attachments for Steam -Boilers, of which the followingis aspecification.

. The object of my invention is to provide an attachment to be used withsteam-boilers of any description, by the aid of. which steam may beproduced of uncommon intensity much more quickly, economically, andsafely than in boilers not provided with my improvement.

The attachment consists, essentially, of a tank provided with anoutlet-pipe, and an inlet-pipe hung from the crownsheet of the boilerinto the fire-box.

In the accompanying drawings, forming part of this specification, Figurel is a perspective view of my improved attachment. Fig. 2 is an endelevation of a locomotive-boiler provided with my improvement. Fig. 3 isa longitudinal section of a locomotive-boiler provided with myimprovement. Fig. 4 illustrates a modification of my device, the samebeing attached to a locomotive-boiler. Fig. 5 shows another modificationof my device attached to a locomotive-boiler. Fig. 6 shows still anothermodifieation of my device attached to an ordinary two-flue boiler.

The tank A is suspended from the crownsheet into the fire-box in suchposition as to be exposed on all sides to the fire. The tank is providedwith a pipe or water-way, B, which extends downwardly from the top ofthe tank nearly to its bottom, connecting the cavity of the boiler withthat of the tank, but lies entirely within the tank and is completelysurrounded by water when the tank is filled therewith. The pipe 0projects from the top of the tank to or above the water-line.

The pipe 0 may be made as shown in Fig. 2, but is preferably constructedas shown in Fig. 3, in which an extension, 0, located in thesteam-space, leads to the front of the boiler and opens in proximity tothe mud-drum.

The water from the boiler fills the tank through the pipe B. The waterin the tank being exposed to the very hottest of the fire is rapidlyconverted into steam, which escapes through the pipe 0, carrying with itwater from the tank, and the place of the steam and Water projected fromthe tank is taken by a fresh supply of water entering through the pipeB. In this way a continuous circulation is kept up. Moreover, the steamand water leave the pipe 0 with great force and induce rapid andtumultuous motion in the contents of the tank and of the boiler.

The mud which would have a tendency to collect in the tank A isprevented by the down current through the pipe 13. Moreover, it isthrust out by the steam and water, and carried forward through theextension 0 to be deposited in proximity to a mud-drum, thusfacilitating the removal of mud from the boiler and preventing theaccumulation of scale.

In the modification shown in Fig. 4 there are two exit-pipes and oneinlet-pipe, and the device is attached to a locomotive-boiler.

In Fig. 6 a device is shown similar to that of Fig. 4, but having thetops of the pipes G curved inwardly, and is applied to an ordi narytwo-flue boiler.

In Fig. 5 another modification of the device is shown applied to alocomotive-boiler. In this modification there are two inlet-pipes andtwo efiluent pipes, the latter having their tops curved inwardly. Theseexit-pipes may be omitted, but it is more preferable to use them inconnection with my device.

I am aware that tanks have been hung from the crown-sheet of boilers,and that these tanks have been provided with inlet and outlet pipes andhave performed functions similar to my own device; but the inlet-pipehas heretofore been so made that three of its sides were made up by theshell of the tank itself, while in my device the inlet-pipe is entirelyseparated from the shell of the tank and is entirely surrounded by thewater in the tank. This arrangesential feature of my invention, and forthe following reason: \Vhen the influent waterway of such a tank hasthree sides of its structure exposed to the direct action of the fireand but one side in contact with the water of ment of the inlet-pipe inthe tank is the esthe tank, its contained water thus acted upon by theheat of the furnace is thrown into violent ebullition, and a column ofsteam thus formed arises with great physical power, and violently andmechanically not only hinders the descending current, but throws acurrent upward more or lessstrongly, so that the cir- IOO culation ofthe water is so much impaired in the tank as to allow the deposit of mudand scales on its bottom, in this way leading to the overheating of themetal, and to its bulging, cracking, and leaking to such an extent as torequire its removal. Such a disaster is not possible where theinlet-pipe, by reason of its being surrounded by water, is notinterrupted in its function of circulation by the rising of aconsiderable column of steam within it. The interior of the tank is keptfree from sedimentary accumulation, and it will last as long as theother parts of the boiler.

\Vh at I claim as new and of my invention, and desire to secure byLetters Patent, is-

1.' As an attachment to a steanrboiler, the tank A, provided with theinlet-pipe B, which CORNELIUS G. OOMEGYS.
